javascript regex for valid month and day not year

if you have more complex date functionality needs, you may also want to check out DateJS, a jquery date validation plug-in.

Here is an even simpler test assuming current year.

FIDDLE

function testDate(dd,mm,yyyy) {
  yyyy = yyyy||new Date().getFullYear(); // optional year
  mm = mm-1; // JS Months are 0 based
  var testDate = new Date(yyyy,mm,dd,12,0,0,0);
    window.console&&console.log(testDate); // remove when happy
  return dd == testDate.getDate() && mm == testDate.getMonth() && testDate.getFullYear() == yyyy;
}

var dd = 29; // your date
var mm = 2; // your month
window.console&&console.log(testDate(dd,mm));

dd = 32; // your date
mm = 13; // your month
window.console&&console.log(testDate(dd,mm));

dd = 2; // your date
mm = 3; // your month
window.console&&console.log(testDate(dd,mm));
